2 Claims.

My invention relates to improvements in egg cartons, the objects of which are to provide means whereby ample rigidity is given to the carton even when made of thinner material than is usually employed in carton manufacturing;

to provide means whereby the longitudinal division may serve to secure the folded ends and act as a stiffener for said carton, and also to provide means, on each carton, which serves to prevent cartons placed side by side from coming into intimate contact with each other, thus affording to the eggs packed therein great protection against damage during shipment. A further object is to provide means for supporting the body of the carton in an elevated position and of providing said means without adding to the amount of card required to make the carton.

The invention consists essentially of a carton having ends folded upon each other and being slotted and a longitudinal division cut at opposite ends to form hook members which are adapted to engage the slotted ends of the carton to hold them in secured position, as will be more fully described in the following specification and shown in the accompanying drawing, in which:-

Fig. 1 is a perspective view of the carton with the cover open.

Fig. 2 is an end view of the carton blank partially folded.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates a blank of suitable material which is creased and folded to form a front wall 2, a bottom wall 3, a rear wall 4, a cover 5 and a lip 6 extending from each end of the front, bottom and rear walls respectively, and integral with the blank are end folds 7, 8 and 9.

Each of the end folds 7, 8 and 9 are slotted as at 10, the slots being so arranged as to be vertical when the carton is folded as shown in Figure 1 and to register with each other and to extend downwardly from the upper edge of the folds to a distance of approximately one half the depth of said folds. The length of the slots 10 will be largely determined by the strength of the material used.

The rear wall 4 of the blank is provided with a plurality of apertures 11 which are preferably formed with one marginal edge in a straight vertical line as at 12 and the opposite edge outwardly curved as at 13, thus making the apertures of greater width at their vertical centre than at their extremities.

A crease 14 is provided on the underside of the blank which extends transversely of the bottom wall adjacent each end so that the first bend of the end folds 8 is downward as at 15 and the second bend is made upwards and parallel thereto, the adjacent or contacting portions forming 1933, Serial No. 661,810

a downwardly projecting rib or leg 16. The fold's 7, 8 and 9 are of the same longitudinal dimension. for the purpose of economy, so that the fold 8 when completed does not extend-to the upper edge of the rear and side walls and obviously its slot 10 is not required to be so deep as the corresponding slots in the folds 7 and 9.

Longitudinal and transverse divisions respectively indicated by the numerals 17 and 18 are provided for insertion into the folded blank, which divisions are slotted as at 19 and 20 in the usual way to permit said divisions to intersect each other and form pockets 21 for the reception of the eggs. At one end of each of the transverse divisions 18 a tongue 22 is formed, which is adapted to project into one of the apertures 11, thus serving to hold the transverse divisions in their appointed places and to project outwardly beyond the rear wall 4 and act as a means for keeping adjacent cartons slightly separated whereby the eggs therein are rendered substantially immune from breakage.

The longitudinal division 1''! is provided at each end with a downwardly turned tongue 23, the throat 24 of which is adapted to be pressed downwardly into the slots 10 of the end folds 7, 8 and 9, thus looking all the folds together and tying the ends of the carton together whereby the carton is materially stiffened, particularly against torsional strain, such as when lifting a filled carton from one end.

The longitudinal division 17 with its tongues 23 holds the folds '7 and 9 into intimate contact with the folds 8, thus holding the two thicknesses of the legs 16 in close contact with each other and add greatly to the strength of said leg, so that the bottom wall being retained above the surface upon which the carton is placed no damage is suffered by eggs being dropped into it.

What I claim as my invention is:

1. An egg carton comprising a blank folded to form bottom, front and rear walls, each of said walls having a slotted extension at each end and forming ends to the carton when folded, the slots being brought into register, and a division extending between said ends secured thereto by hook members on the division passing through said slots.

2. An egg carton comprising a blank folded to form bottom, front and rear walls, each of said walls having a slotted extension at each end and folded inwardly to form ends to the carton with the slots in register, the extensions to the bottom wall being first folded downwardly and then upwardly to form a transverse leg to the carton and a division having hooks extending between the front and rear walls adapted to engage the slots and secure the folded extensions together at each end of the carton.
